PARTING STRIP FOR WINDOWS.

Application filed October 14, 1922. Serial No. 594,436.

To all whom t may concern.'

Be it vknown that I, FREDERICK EHRSAM, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Parting Strips for Windows, of which the following is a speciication.

This invention relates to improvements in windows, and it pertains more particularly to the construction of the parting strip, and its application to a window.

'Ihe object in the present instance is to provide a simple, and eifective parting strip, which will serve the double purpose of a weather proofing attachment and also an anti-rattler for windows, and it is intended primarily as an improvement on the device illustrated and described in Letters Patent No. 1,288,623, which discloses a rockably mounted parting strip.

In applying parting strips such as described in the above noted patent, the most outstanding difficulty has been to accommodate the channel bar to the groove in the window frame. These grooves vary in width and depth, and more than ordinary skill is required to properly install the strips.

I have overcomethis objection in my present construction, and have provided a strip capable of being installed by any person, even the unskilled.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in whichz- Figure 1 is a cross-sectional view of one side of a window casing with my improved strip applied thereto.

Figure 2 is a longitudinal sectional view thereof.

Figure 3 shows a portion of the strip plate in perspective view.

The numeral 1 designates one side of a window casing, 2 designates the usual pulley stile, 3 designates the outer stop and 4 the inner stop; 5 designates the sash.

The window frame is usually provided with longitudinal grooves, 6, and I utilize each groove as a receptacle for the parting strip plate.

The parting strip plate is made of some suitable, moderately soft metal, such as sheet zinc, and it is bent into the form illustrated in Fig. 3, that is, approximately T-shape.

The parting strip platel 7, is of such a width as to span the open side of the groove 6, and it is secured to the inner face of the stile along both sides, by tacks, brads or other fastening means 8. The bent or U- shaped portion 9 of the plate lies Within' the groove 6 and against one of the inner walls thereof, extending into the groove sulficiently far to provide a certain rigidity, but not contacting with the base of the groove, so as to insure complete contact between the plate and the face of the stile and making the device applicable to any window frame provided with a groove. The plate Will also permit of a sufficient degree of adjustment to secure satisfactory results when the distance from the edge of the groove to the face of the sash varies, for the reason that the plate may be moved back, so that the projection leaves its contact with the groove wall, until the strip bears against the sash with just the desired friction or pressure, and when that point is attained, the plate is tacked to the stile along the edges, as indicated in the drawing. This securing means will also permit of its easy removal, While it will positively insure against its accidental removal, as is the case where a channel or other friction engagement is depended upon.

In some instances however, it may be found desirable to form the plate without the projecting portion, using a flat plate, wide enough to span and form a vclosure for the groove.

. In either case, the parting strip is attached to the plate in the usual manner, that is, through the screws or other means provided for securing the springs 11 to the strips. This feature of the springs carried by the strips is identical with that shown in the patent above noted, and consists of flat leaf springs l1 secured to and carried by the parting strips and adapted to lie within the grooves 6 of the frame.

In the present instance I dispense with the channel bar of said patent, and use merely the strip plate, and this plate, attached to the parting strip, may be made in any length, so that the desired length required in each instance may easily be cut therefrom, because of the soft metal used.

In applying my strip, it will be necessary only to place the plate over the groove, and, where the plate is provided with the bead or bent portion, to place said bead against one wall of the groove, and fasten the plate in position by tacks. The strip Will bear normally against the inner face of the sash 5 and its engagement'with the frame Will he secure.

I-Iaving thus described. my invention, I claimz# l. In a Window construction, a Window frame formed with a groove in its jamb, a plate of relatively soft metal forming a elo sure for the groove and of a Width greater than that of the groove, said plate having a projection thereon which extends into the groove anol lies normally against one Wall thereof but does not Contact with the base of the groove, a strip of Wood rookaloly mounted on the plate, a Window sash, and

means for keeping the strip in Contact with the sash.

2. In a window construction, a frame having a groove in its jamb, aplate of soft metal forming a closure for the groove, said plate being Wider than the Width of the groove and having means for securing it to the jamb along one edge of the groove, a projection formed on the plate disposed Within the groove but not in Contact With the bottom thereof, a strip of Wood Carried by the plate, a Window sash, and spring means for keeping the strip normally in Contact With the sash.

In testimony whereof I ailix my signature.

FREDERICK EHRSAM.
